LLV.V
The fiber optic distributor supply LLV.V is the basic component for the fiber optic system. It serves
to connect star distributors and to amplify the light signals received. Its power supply is sufficient
for supply of five fiber optic distribution components of the type LLV.4.
The amplification of LLV.V in the fiber optic data path is sufficient for increasing the distance for
each LLV.V by about 50 m, so that overall longer transmission paths are possible then.
LLV.4
The fiber optic distributor LLV.4 is connected to the base component LLV.V. It is able to distribute
the optical signal to respectively receive from four connections and therefore multiplies the signal
from the computer to Thyro-P by four units each. The maximum distance from LLV.4 to Thyro-P
should not exceed about 25 m.
In case of optimum installation conditions (number of bends, connection mounting, etc.), the dis-
tances stated in the following table may be realized:
DEVICE PC LLV.V LLV.4 THYRO-P
PC – – 50 m – – 25 m
LLV.V 50 m 50 m – – 25 m
LLV.4 – – 50 m – – 25 m
Thyro-P 25 m 25 m 25 m – –
